ABSTRACT:
There is provided a locking device for fastening a wing element where rotation of a rotor (13) effects smooth locking and unlocking of a wing element and also enables it to smoothly open and close free from interfering with a rocking arm (24); in operation rotation of the rotor (13) causes a slide cam (6) to move linearly rearward so that body (3) is rotated through a pivot (17) into an upright position, and a front-end pushing portion (18) of the arm (24) abuts on a support portion (20) of a stationary frame (19); rotor (13) is prevented from dropping out of the body (3) by ball bearings (15) rotatably mounted between annular grooves (14,9) of the body (3) and of the rotor (13); and a spring (25) rotatably biases the arm (24) to cause a base-end follower portion (23) of the arm (24) to abut on a rear-end surface of the slide cam (6).
